Extruded aluminum heat sink housing structure for an internal rotor motor

Abstract

This utility model relates to the field of motor housing technology, and more particularly to an extruded aluminum heat dissipation housing structure for an internal rotary motor. The structure includes multiple heat dissipation fins fixedly installed on the surface of the housing, multiple through holes fixedly installed on the bottom of the housing surface, and a rear cover movably installed on the inner side of the bottom of the housing. This utility model secures the rear cover to the bottom of the housing by adapting it to the interior of the housing and tightening it sequentially into the through holes and threaded holes with locking screws. This allows for a detachable connection between the rear cover and the housing. Therefore, when either the rear cover or the housing is damaged, only the corresponding part needs to be replaced, eliminating the need for a complete replacement. Furthermore, the removal of the rear cover facilitates the disassembly and assembly of the stator and rotor structure inside the housing, simplifying maintenance. Since the rear cover and housing are detachable and not integrally formed, the housing can be processed using small-tonnage aluminum extrusion equipment.
